Offset date for a Pandas DataFrame date index

Question

Given a Pandas dataframe created as follows:

dates = pd.date_range(\'20130101\',periods=6)
df = pd.DataFrame(np.random.randn(6),index=dates,columns=list(\'A\         


        

Answer 1

you can use DateOffset:

>>> df = pd.DataFrame(np.random.randn(6),index=dates,columns=list('A'))
>>> df.index = df.index + pd.DateOffset(days=15)
>>> df
                   A
